vimUtils: remove vam support
having this many (complex) options not only is hard to maintain but I cant see the benefit of these options now that vim supports packages

## Managing plugins with VAM {#managing-plugins-with-vam}
|
||||
|
||||
### Handling dependencies of Vim plugins {#handling-dependencies-of-vim-plugins}
|
||||
|
||||
VAM introduced .json files supporting dependencies without versioning
|
||||
assuming that "using latest version" is ok most of the time.
|
||||
|
||||
### Example {#example}
|
||||
|
||||
First create a vim-scripts file having one plugin name per line. Example:
|
||||
|
||||
```vim
|
||||
"tlib"
|
||||
{'name': 'vim-addon-sql'}
|
||||
{'filetype_regex': '\%(vim)$', 'names': ['reload', 'vim-dev-plugin']}
|
||||
```
|
||||
|
||||
A discrete vim-scripts file can be read by VAM as well like this:
|
||||
|
||||
```vim
|
||||
call vam#Scripts(expand('~/.vim-scripts'), {})
|
||||
```
|
||||
|
||||
Create a default.nix file:
|
||||
|
||||
```nix
|
||||
{ nixpkgs ? import <nixpkgs> {}, compiler ? "ghc7102" }:
|
||||
nixpkgs.vim_configurable.customize { name = "vim"; vimrcConfig.vam.pluginDictionaries = [ "vim-addon-vim2nix" ]; }
|
||||
```
|
||||
|
||||
Create a generate.vim file:
|
||||
|
||||
```vim
|
||||
ActivateAddons vim-addon-vim2nix
|
||||
let vim_scripts = "vim-scripts"
|
||||
call nix#ExportPluginsForNix({
|
||||
\ 'path_to_nixpkgs': eval('{"'.substitute(substitute(substitute($NIX_PATH, ':', ',', 'g'), '=',':', 'g'), '\([:,]\)', '"\1"',"g").'"}')["nixpkgs"],
|
||||
\ 'cache_file': '/tmp/vim2nix-cache',
|
||||
\ 'try_catch': 0,
|
||||
\ 'plugin_dictionaries': ["vim-addon-manager"]+map(readfile(vim_scripts), 'eval(v:val)')
|
||||
\ })
|
||||
```
|
||||
|
||||
Then run
|
||||
|
||||
```bash
|
||||
nix-shell -p vimUtils.vim_with_vim2nix --command "vim -c 'source generate.vim'"
|
||||
```
|
||||
|
||||
You should get a Vim buffer with the nix derivations (output1) and vam.pluginDictionaries (output2).
|
||||
You can add your Vim to your system's configuration file like this and start it by "vim-my":
|
||||
|
||||
```nix
|
||||
my-vim =
|
||||
let plugins = let inherit (vimUtils) buildVimPluginFrom2Nix; in {
|
||||
copy paste output1 here
|
||||
}; in vim_configurable.customize {
|
||||
name = "vim-my";
|
||||
|
||||
vimrcConfig.vam.knownPlugins = plugins; # optional
|
||||
vimrcConfig.vam.pluginDictionaries = [
|
||||
copy paste output2 here
|
||||
];
|
||||
|
||||
};
|
||||
```
|
||||
|
||||
Sample output1:
|
||||
|
||||
```nix
|
||||
"reload" = buildVimPluginFrom2Nix { # created by nix#NixDerivation
|
||||
name = "reload";
|
||||
src = fetchgit {
|
||||
url = "https://github.com/xolox/vim-reload";
|
||||
rev = "0a601a668727f5b675cb1ddc19f6861f3f7ab9e1";
|
||||
sha256 = "0vb832l9yxj919f5hfg6qj6bn9ni57gnjd3bj7zpq7d4iv2s4wdh";
|
||||
};
|
||||
dependencies = ["nim-misc"];
|
||||
|
||||
};
|
||||
[...]
|
||||
```
|
||||
|
||||
Sample output2:
|
||||
|
||||
```nix
|
||||
[
|
||||
''vim-addon-manager''
|
||||
''tlib''
|
||||
{ "name" = ''vim-addon-sql''; }
|
||||
{ "filetype_regex" = ''\%(vim)$$''; "names" = [ ''reload'' ''vim-dev-plugin'' ]; }
|
||||
]
|
||||
```
|
||||
|
||||
## Adding new plugins to nixpkgs {#adding-new-plugins-to-nixpkgs}
|
||||
|
||||
Nix expressions for Vim plugins are stored in [pkgs/applications/editors/vim/plugins](https://github.com/NixOS/nixpkgs/tree/master/pkgs/applications/editors/vim/plugins). For the vast majority of plugins, Nix expressions are automatically generated by running [`./update.py`](https://github.com/NixOS/nixpkgs/blob/master/pkgs/applications/editors/vim/plugins/update.py). This creates a [generated.nix](https://github.com/NixOS/nixpkgs/blob/master/pkgs/applications/editors/vim/plugins/generated.nix) file based on the plugins listed in [vim-plugin-names](https://github.com/NixOS/nixpkgs/blob/master/pkgs/applications/editors/vim/plugins/vim-plugin-names). Plugins are listed in alphabetical order in `vim-plugin-names` using the format `[github username]/[repository]@[gitref]`. For example https://github.com/scrooloose/nerdtree becomes `scrooloose/nerdtree`.
